Katherine Pierce

Katherine Pierce (based on Katherine von Swartzschild from the novels) is the main antagonist of the series, being a major antagonist in the first, second, fourth, fifth and eighth seasons of the show and a minor antagonist/anti-hero in the third season. She is the ancestor and doppelgänger of Elena Gilbert and the doppelgänger of Tatia and Amara. Katherine Pierce, born as Katerina Petrova on June 5, 1473, to a Bulgarian family but was disowned after having a child out of wedlock. She fled Bulgaria and reached England, where she met Klaus Mikaelson and his brother Elijah, members of the Original Vampire Family. She was attracted to Elijah but was horrified when she found out that Klaus planned to sacrifice her for a ritual. So, she charmed Trevor, a young man, and used him as a means of escape. This led to him sending her to Rose-Marie (a vampire). Rose was shocked after hearing Trevor's betrayal and afraid of Klaus, told Katerina that she would turn her over to Klaus. This led to Katerina committing suicide, ultimately stabbing herself, forcing Rose to heal her with vampire blood. When Trevor arrived and Rose got distracted while talking to him, Katerina seized the opportunity and hung herself, successfully turning into a vampire by feeding on the human host of the house. Thereby sabotaging Klaus' plan because she was no longer human and her blood no longer was a viable component of the ritual to undo the curse. She then flees the place after taking a moonstone with her. Klaus was so infuriated with Katerina's sabotage that she was forced to live on the run for over 500 years as he hunted her down. In 1864, she arrived at Mystic Falls, staying with The Salvatores and gaining their trust. Eventually she lured both the Salvatore Brothers, played and used both them before feeding them her blood. Throughout the series, she claims that she loves Stefan Salvatore.
